The 8th planet : Neptune.
Neptune
A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large planet that is not primarily composed of solid matter. There are four gas giants in the Solar System: Jupiter, Saturn, Uranus, and Neptune.
Uranus has the surface area of 15.91 Earths. It has the volume of 63.086 Earths. It has the mass of 14.536 Earths. Its diameter is 4.007 times that of Earth. See the related link for more information.
Uranus has multicolored rings around it. You can find this answer elsewhere , in places such as an encyclopedia , or a science textbook. Uranus' rings are up and down unlike the other planets. Saturn also has rings that are very visiable , but do not have as much color as Uranus. Thank you for asking this question.Uranus , The Planet
Neptune and Uranus (tee-hee) are the only two ice giants in our solar system.
There are four planets in our solar system that have ring systems. The most obvious, and dramatic, example is Saturn with it's many complex rings and ring divisions. Jupiter also has a fairly faint ring system, first discovered in 1979. The rings of Uranus are quite well defined, and were the second system of planetary rings discovered in our solar system. Finally, Neptune has a very tenuous set of rings that are mainly small, dark particles of dust.

Neptune
Astronomers had noticed unexpected changes in the orbit of Uranus: the only explanation was another planet. Detailed study of the orbit of Uranus led to estimates about the size and location of Neptune.
Neptune
scientist discovered that Uranus was hit over by a massive object that tilted the planet over. because of that Uranus is tilted almost 90 degrees and lies on it side !
Astronomers now realize that Pluto does not have nearly enough mass to noticeably affect the orbits of Uranus or Neptune.
Ya mum.
Irregularities in Uranus's orbit.
Astronomers aren't sure why. Uranus may have been involved in a collision with another large object. We don't know.
Astonomeres have made the calculation of 27 moons and their calculatoins were right tere are 27 moons on Uranus
Astronomers predicted the existence of Neptune because they observed irregularities in the orbit of Uranus that couldn't be explained by the known gravitational forces in the solar system. By calculating the disturbances in Uranus's orbit, astronomers were able to predict the location of another planet (Neptune) exerting gravitational influence on it. This theoretical prediction eventually led to the discovery of Neptune in 1846.
